hi

I have a gridview with two columns that contain a textbox each that i would like to validate. Each row also contains an imagebutton that does some action. How do i make it so that it only validates for the specific row that the button was click?

Is OptionID a unique field for each row?

You could add a validationgroup to your validators and imagebutton, something like:

ValidationGroup = 'row<%#Eval("OptionID")'

This should create a unique validation group for each row and ensure the validators only act on the controls in their own row.

Note i had to dynamically add ValidationSummary controls for each row in for the validation to show the error message.
